- The exit probe was not appropriately filtered to only the known pid so it was firing on any random process that would exit rather the only the one we cared about. - The dtest script executes the tst.raise*.exe in the background from POSIX sh without jobs control. POSIX mandates that SIGINT be set to SIG_IGN in this case. The test executable never actually tested that SIGINT could be caught despite trying to block and delay the signal. So the SIGINT sent from raise() is never actually received since it is ignored. This could be fixed by calling 'trap - INT' from dtest before running the executable but I've opted to just use SIGUSR1 instead in these specific tests rather than adding more logic to test that SIGINT is not ignored at startup. These 2 issues meant that the tests would randomly work but only if a process coincidentally exited during the test. Reviewed by: markj MFC after: 2 weeks Sponsored by: Dell EMC Isilon

For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information).
The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7) and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables.
The buildkernel and installkernel targets build and install
the kernel and the modules (see below). Please see the top of
the Makefile in this directory for more information on the
standard build targets and compile-time flags.
Building a kernel is a somewhat more involved process. See build(7), config(8), and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html for more information.
Note: If you want to build and install the kernel with the
buildkernel and installkernel targets, you might need to build
world before. More information is available in the handbook.
The kernel configuration files reside in the sys/<arch>/conf
sub-directory. GENERIC is the default configuration used in release builds.
NOTES contains entries and documentation for all possible
